Final answer:
In the context of healthcare, an individual receiving medical care in a hospital is commonly referred to as a patient.
Step-by-step explanation:
A person receiving care in a hospital is usually called a patient. While terminology such as client, customer, or visitor may be used in different contexts within various service industries, within the context of healthcare, particularly in settings like a nonprofit health organization, a private hospital, or a governmental agency like Health and Social Services, the term 'patient' is the appropriate word to describe someone who is being treated by doctors or nurses.
